BEFORE PROGRAMMING THE Z400B.

KEY FUNCTIONS

BATTERY SWITCH

Slide to “ON” before any scheduling is made.

RUN-SET Slide Switch

Allows the user to choose in the RUN MODE the function

that will be reviewed. In the SET MODE the MODE

SELECT key will allow the user to step through or choose

the functions to be set or changed. i.e. Schedule, Astro, etc.

Appropriate light indicator will allow the user to know what

function is being accessed.

REVIEW

In the RUN MODE, the REVIEW KEY serves to review the

functions available in the unit by stepping through it. In the

SET MODE, the REVIEW KEY serves to display the entries

that may be either left alone or deleted.

DELETE

The SET MODE allows the user to DELETE any entries

while reviewing.

ADVANCE (ADV)

In the SET MODE, the ADV KEY serves as a cursor in

order to move through the information displayed in the front

panel. It is a “STEP” key that allows you to move through

the different data that was entered, such as channels, time

of operation, days of the week, etc.

ENTER

Sets the information being entered into the unit’s memory.

PROGRAMMING SUMMARY

RUN MODE

Displays the current time (AM/PM format only), day of

week, and channel status as per schedule. In this mode,

the user can review all the following menus without

accidental modification:

YEAR DATE TIME

HOLIDAY

SCHEDULE

OVERRIDE

ASTRO

SET MODE

In the SET MODE, flashing LED’s guide user at the

appropriate times, to enter, change, review or delete

data in the five modes listed above. A flashing

channel LED, for example, is asking the user to enter

a new channel # or use the one that is flashing. Also,

a pair of flashing colons are asking for data entry into

display which could be year, date, time, etc. This

feature is the keynote to programming the unit.

Another feature is that any new entry or changes

(note that data entry/change is possible in the SET

MODE) will become active only when the SET/RUN

switch is moved from SET to RUN position. However

any existing entries would continue to be executed

while the SET/RUN switch was in the SET position.

After setting schedules and other data the SET/RUN

switch is moved to the RUN position. The unit will

then execute the true status of the circuits and no

manual ON/OFF is necessary.

The same will happen when the user sets a new

time; the circuit status would be current immediately.

(Look back feature).

Any time a key is pressed an audible signal is

generated (one beep). Every time the entry or

information is entered into the unit’s memory a

double beep signal will be generated. Errors will

generate a multiple-beep signal.

In order for any channel to execute its schedule, the (ON-

AUTO-OFF) switch must be in the AUTO POSITION.

OPERATING GUIDE

SETTING THE SCHEDULES

Be sure battery switch is ON.

It is advisable to first layout schedules on the schedule

sheets supplied.

IMPORTANT: TO SET DAYLIGHT SAVINGS TIME,

PLEASE SEE ADDENDUM ON PAGE 7 AND EXECUTE

PRIOR TO SETTING SCHEDULES..

If the unit was started for the first time or if memory is

empty, the display shows a flashing SUN 12:00.

If the unit display shows a specific time indicating it retained

old time and data, then proceed with DATE TIME SET or

press the reset button to rid the unit of all data and start

fresh. (See page 1 — clear all memory.) Use a ballpoint

pen or end of a paper clip. Press gently.

Move the SET/RUN switch to the SET position. Be sure

battery switch is on.

YEAR DATE TIME SET

Press MODE SELECT until YEAR DATE TIME LED is lit

constantly (no flashing). The colon will be flashing and 4
